VENTILATOR FORVEHICLES.

Specification of Letters Patent.

Patented Oct. 26, 1909.

To all whom it may concern:

other matter that might enter the car or veie it known that I, F RANK R.HARVEY, a hicle.

citizen of the United States of America, residing at Pittsburg, in thecounty of Allegheny and State of Pennsylvania, have invented certain newand useful Improvements in Ventilators for Vehicles, of which thefollowing is a. specification, reference being had therein to theaccompanying drawing.

This invention relates to ventilators for vehicles, and the primaryobject of my invention is to provide in manner as hereinafter set fortha novel ventilator for admitting fresh air to the interior of the vehi-le and extracting foul air therefrom.

Another object of this invention is to provide a simple and inexpensiveventilator that will be actuated by air set in motion by the tin-wardmovement of the'vehicle.

A further object of this invention is to provide a ventilatorparticularly designed for passenger coaches and Pullman cars forremoving smoke and foul air from the interior of the coach or car,insuring a thorough ventilation and perfect comfort of the occupants ofthe car.

A still further object of my invention is' to provide a ventilatorcomprising a horizontal revoluble fan having bearings that will reducethe friction of the fan when in operation to a minimum and therebyinsure a positive operation of the fan for the functions prescribed forsaid fan.

A still further object of this invention is to provide a ventilator thatcan be advantageously used in connection with window screens,particularly the screens used in the windows of Pullman berths forthoroughly ventilating a berth and insuring perfect comfort to theoccupants thereof in the warmest kind of weather.

A still further object of this invention is to provide novel means inconnection with a ventilator of the above type for retaining the same ina closed position and preventing rain, snow or foreign matter fromentering the interior of the car or vehicle.

A still further object of this invention is the provision of novel meansin connection with a ventilator of the above type that will pocket ordeflect air toward the ventilator and at the same time exclude snow,rain and A still further object of the invention is to provide a strongand durable ventilator that can be applied to a car or vehicle withoutmaterially changing the construction of the car or vehicle.

lVith the above and other objects in view which will more readily appearas the invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts to be hereinafterdescribed and then specifically claimed.

Referring to the drawings :Figure 1 is a plan of a wind ow screenshowing the adaptation therewith of a ventilator in accordance with thisinvention, Fig. 2 is a sectional View on line 0-0 of Fig. 1, Fig. 3 is ahorizontal sectional view on line /l-(:l of Fig. 2, Figs. at and 5 aredetails of a locking pin used in connection with the ventilator asapplied to window screens, and Fig. 6 is a perspective view of aventilator in accordance with this invention.

Referring to the drawings in detail, the adaptation of the ventilator isshown in connection with a window screen 27 commonly used in the windowframes of Pullman cars and is provided with a ventilating fan. Thescreen frame 27 is provided with keepers 28 and adapted to engage insaid keepers are the hangers 29 of an open-ended hood 30. In the hood 30is journaled a horizontally revoluble bladed fan 31 adapted to force airthrough the screen frame 27 and ventilate the coach and a berth made upin said coach.

To look the fan to close the opening 2 and prevent air from being forcedinto the vehicle, a latch 32 is used adapted to engage in a keeper 33carried by one of the blades of the fan. The latch can be located uponthe frame 1 to hold one of the vertical edges of the fan, or upon thebottom rail of the frame 1 to hold the lower edges of the fan.

The lock used in connection with the fan 31 of the detachable hood 30comprises a springpressed pin 34: mounted in a depending enlargement 35of the screen frame 27. This pin is adapted to protrude into the hood 30and prevent the fan 31 from rotating. The pin 34 can be locked in or outof engagement with the fan 31, by a lug 36 carried by said i i v i p111for engaglng the outer side of the enlargement 35.

My invention in its broadest as Ject comprehends means (frame and hoodfor detachably holding a ventilating fan relative to an opening in acar, whereby fresh air will be forced into the car and foul airexpelled, thus maintaining the interior of the car in a sanitarycondition, particularly smoking and sleeping compartments.

lVhile in the drawings forming a part of this application there isillustrated the preferable form of construction, I would have itunderstood that the elements therein can be varied or changed as toshape, proportion and manner of assemblage without departing from thespirit of the invention.

Having noW described my invention What I claim as new, is

In a ventilator, a frame having an' open ing, a revoluble fan supportedrelatively to said opening for carrying air therethrough as the fanrevolves, keepers carried by said frame, and a hood open at both endsand. along its inner side, said hood inclosing the fan, and hookscarried by the hood andengaging the keepers carried by the frame forsupporting the hood.

In testimony whereof I aiiix my signature in the presence of twoWitnesses.
